Question

That guy this question is evil help

Answer 1

450 mins per night

Explanation:

average =
`(sum \: of \: terms)/(number \: of \: terms)`

average = (8 + 6.5 + 7 + 8.5)/4

average = 30/4

average = 7.5

The average is 7.5 hrs.

Convert hrs to mins.

7.5 × 60 = 450

Answer 2

450 mins/night

Explanation:

The average of a data set is the sum of all of the data divided by the number of data elements in the set. In this case, that would be:

(8 + 6.5 + 7 + 8.5) / 4

= 30 / 4

= 7.5 hours

7.5 hours is 7.5 * 60 = 450 mins/night
